Baltimore County Executive Johnny Olszewski

John “Johnny O” Olszewski, Jr. is a lifelong Baltimore County resident who believes in the power of public service and giving back to a community that has done so much for him. He is a graduate of Sparrows Point High School, earned his undergraduate degree from Goucher College and earned a master’s degree from The George Washington University. Last December, Johnny earned his Ph.D. in Public Policy from the University of Maryland Baltimore County.

Starting Off Strong

Johnny was elected in 2006, at age 23, as the top vote getter to the Maryland House of Delegates from Legislative District 6 and re-elected four years later. He served in the House of Delegates for nearly nine years. His work earned him a reputation as a “rising star” of Maryland politics—and helped breathe new life into the abandoned steel mill in his hometown. 

In the legislature, Johnny served as the Chairman of the Baltimore County House Delegation and was the youngest person ever elected to that position. In that capacity, he helped lead unprecedented progress for the County in areas such as economic development and school board reform. As a staunch advocate of working families, Johnny led the charge on earned sick leave and raising the minimum wage, and offered a critical vote in securing Marriage Equality in the State of Maryland.

Johnny lead Baltimore County’s House Delegation and he served on the House Economic Matters Committee, Maryland’s P-20 Leadership Council, the Maryland Business Climate Workgroup and as Chair of the Banking, Economic Development, Science and Technology subcommittee.

Committed to Baltimore County's Future

Johnny is a former student member of the Baltimore County Board of Education, a 2010 graduate of Leadership Baltimore County and was recognized as one of the Daily Record’s “Top 20 in their 20s” in 2012. He is an active philanthropic and economic development leader who has served as a member of the Business Network for Offshore Wind board, the Community College of Baltimore County’s Dundalk Foundation board and the Goucher College Board of Trustees. Before his election to Baltimore County Executive, Johnny worked in the private sector at SAS Institute, where he partnered with governments to help prevent fraud, enhance public safety, improve program performance and enable greater transparency.

Family Values

Johnny lives in Dundalk with his wife Marisa and their daughter Daria. The Olszewski family is active in their church and maintains strong ties as volunteers in their community and across Baltimore County.
